1.6 Troubleshooting
If you encounter a hardware problem, review the following suggestions before calling for
service.

General Failure

• Are all cables securely plugged in?
• Are all system components and peripherals turned on?
• Is the system main power switch on?
• Is the power outlet burned out? You may check this by plugging in and turning on
some other piece of equipment.
• Are any cables damaged? Are they properly routed and coiled? Entwined cables may
cause signal interference.

Front Panel Light Doesn't Work

• Check inside the system unit and make sure that the front panel LED connector is
correctly plugged in (refer to section 2.3 Jumpers and Connectors).

"Garbage" or Nothing Appears on the Screen

• Is the monitor turned on? Is the screen brightness adjusted properly?
Never open the monitor case. The CRT monitor
retains very high voltage levels, even after the
power is turned off. Refer all monitor service to
qualified service technicians.
